Behaviour Interactive Backend Engineer interview questions & guide 2026

The questions below represent the patterns observed in recent interview cycles. While the specific technical focus may shift depending on whether you are interviewing for a live service or a new project, the core themes remain consistent.

Technical Proficiency and Coding

These questions assess your ability to write clean, efficient code and your understanding of fundamental software engineering principles.

• Implement an algorithm to reverse a string.
• Explain your approach to solving complex algorithmic problems under pressure.

Preparation for Behaviour Interactive requires a balanced focus on deep technical mastery and clear, professional communication. You should approach your preparation by thinking through your past projects not just as a series of tasks, but as a series of architectural decisions.

Technical Depth – You must be comfortable discussing the "how" and "why" behind your code. Interviewers look for candidates who understand the trade-offs of their chosen technologies and can explain them clearly.

Problem-Solving Methodology – When faced with an algorithmic challenge, your process is as important as the final output. Be prepared to communicate your thinking out loud as you work through whiteboard or coding exercises.

Communication and Collaboration – You will often work in cross-functional teams. Demonstrating that you can explain complex technical concepts to peers and project managers is essential for success.

Cultural Alignment – Behaviour Interactive values passion for the craft of game development. Showing an genuine interest in their specific products and their approach to the industry will set you apart.

The interview process at Behaviour Interactive is designed to be thorough, evaluating both your technical rigor and your fit within the studio's collaborative culture. You can typically expect a multi-stage journey that begins with an initial screening and progresses toward more intensive technical evaluations.

The process often starts with an HR conversation to align on expectations, followed by a technical assessment—either a take-home coding challenge or a live coding session. Final rounds usually involve meeting with technical leads and management to discuss your architectural experience and team compatibility. The pace is generally professional and structured, with a clear focus on verifying that your skills meet the high standards of their production environments.

This timeline illustrates a standard progression from initial screening to final technical review. Candidates should interpret these stages as an opportunity to demonstrate different facets of their expertise, moving from high-level interest to deep technical execution. Use the time between stages to refresh your knowledge of core computer science fundamentals and the specific technology stack mentioned in your job description.

Algorithmic Problem Solving

This is a standard component of the technical screen. You are evaluated on your ability to produce working code, but also on your ability to optimize for time and space complexity.

Be ready to go over:

• Common data structures (arrays, hash maps, trees).
• String manipulation and array traversal.

As a Backend Engineer, you will be responsible for the development and maintenance of server-side features that directly impact player experience. You will collaborate closely with game designers and client-side engineers to ensure that the backend architecture supports the gameplay vision. This includes designing robust APIs, managing high-volume data storage, and ensuring the stability of game services under load.

You will spend a significant portion of your time troubleshooting production issues and optimizing performance bottlenecks. You are expected to participate in code reviews, contribute to technical documentation, and mentor junior team members as you grow within the role. The work is iterative, requiring you to adapt quickly to feedback from internal playtests and live data analytics.

A competitive candidate for the Backend Engineer position at Behaviour Interactive will demonstrate a strong grasp of server-side programming and a professional approach to software development.

• Must-have skills: Proficient in modern backend languages (e.g., C++, C#, or JavaScript/TypeScript), experience with RESTful APIs, and a solid understanding of database systems (SQL/NoSQL).
• Nice-to-have skills: Experience with cloud infrastructure (AWS/GCP), knowledge of game engine backend integration, and proficiency in French.
• Experience level: Typically, mid-to-senior level roles require a demonstrated history of delivering scalable backend solutions.
• Soft skills: Strong communication, a collaborative mindset, and the ability to thrive in a fast-paced, deadline-driven environment.

Q: How long should I prepare for the technical assessment? A: Dedicate at least one to two weeks to reviewing core computer science fundamentals and common algorithmic problems. Practice coding in your preferred language until you can explain your logic fluently.

Q: Does the interview process vary by project? A: Yes, the specific technical requirements may shift depending on whether the team is working on a new, unannounced project or a live service. Always tailor your preparation to the specific stack mentioned in the job posting.

Q: Is proficiency in French mandatory? A: While English is the primary language for most technical documentation, Behaviour Interactive is a Montreal-based company, and French proficiency is considered a significant asset.

Q: What is the typical timeline for an offer? A: While it varies, candidates can generally expect the process from the initial screen to a final decision to take several weeks. Stay engaged and follow up professionally with your recruiter.

• Understand the Studio: Research the games Behaviour Interactive has developed. Understanding their product portfolio helps you frame your answers in the context of their specific engineering challenges.
• Master the Basics: Do not overlook fundamental data structures. Even for senior roles, the ability to write clean, efficient code on a whiteboard or in a live test is a baseline expectation.
• Be Transparent: If you don't know the answer to a specific technical question, explain your reasoning process or how you would go about finding the answer. Honesty is valued over guessing.
• Prepare Questions: Always have 3-5 thoughtful questions for your interviewers about the team’s current tech stack, their biggest engineering hurdles, or the company culture.

The Backend Engineer role at Behaviour Interactive is an exceptional opportunity to contribute to high-impact gaming infrastructure. By focusing on your technical fundamentals, system design capabilities, and clear communication, you can confidently navigate the interview process. Remember that the interviewers are looking for a teammate who balances technical expertise with a passion for the player experience.
